Automatic balancing apparatus

An automatic balancing apparatus in combination with a rotator body, the rotator body having a rotary shaft defining an axis of rotation, the automatic balancing apparatus comprising:

• a plurality of balancing members rotatable about the rotary shaft, each of the balancing members having a balance action section spaced a distance in a radial direction from the axis of rotation, wherein the balance action sections do not contact one another and a connection section that rotatably couples the balance action section to the rotary shaft;
• wherein the connection section has a generally uniform width along a longitudinal direction extending radially outward from the shaft to the unbalance section;
• and
• wherein the balance action section has a mass that effects a balance correction action to cancel a rotational unbalance of the rotator body when the rotator body rotates at a rotational speed that exceeds its resonant rotational speed, and the connection section has a mass that effects a balance correction action to a degree substantially less than the mass of the balance action section.
